How can you decide what passage of a book to read in a presentation. I read "Amy Snow" but don't remember which pages were significant
What thoughts do you have about the story? Did it prompt you to ask questions about the world you live in? Did it give you any insight into the lives of other people (other than yourself and your family)? Did it help you see the world and the people in it in a different way than you did before you read it? Did it change your perspectives in ANY way at all? If so, how? What was in the story that seems to have done that? Once you have thought about it, what can you go to within the story that reinforces your viewpoint? Then you can leaf through the book (unless it's an ebook) and find those incidents in the story or those passages that particularly impressed you.
If it was just a good story that entertained you, all the same things apply. What in particular was funny or sad or illuminating?
